RESPONSE: Date extended per amendment 0001.

10) Please state the correct name for the Solicitation. Reads different in various solicitation documents.

RESPONSE: Official title is stated on the Plans and Specifications covers.

11) Refer to Solicitation Proposal Requirements- Tab 3: Subfactor 3 Small Business SBPCD The SB requirement is 25% of TCV. Clarify if 5% minimum of TCV (part of the 25% minimum TCV total), should be indicated in one or any the following categories: VOSB; SDVOSB; Hubzone; WOSB.

RESPONSE: SBD: Must have a Minimum of 5%

12) it’s our understanding this solicitation is a Indefinite Quantity as stated in Bidding Schedule Notes #8, see below for a quick reference. In this note it states that information concerning Indefinite Quantity can be found in section 00700 “Contract Clauses”, however we could not find this section in either “A22- 19R0032 – Solicitation” or “A02 – 19R0032-AdvSpecs”.

Information concerning indefinite quantity contracts, as well as the issuance and limitations of delivery orders may be found in Section 00700, Contract Clauses.

RESPONSE: Please refer to the following Contract Clauses located in SECTION 00 07 00 - Conditions of the Contract:

52.216-18 Ordering Page 45 of the Solicitation 52.216-19 Order Limitations Page 45 of the Solicitation 52.216-22 Indefinite Quantity Page 46 of the Solicitation

13) Spec Sec 00 08 00-1.22-I first states that all work shall be done from the downstream side of the dam, but then later in the same paragraph talks about being able to be upstream of bulkheads. Please clarify the USACE intent of this statement.

RESPONSE: Section revised per amendment 0001. Specification Section 00 08 00 -1.22 (i.) now states, “All work by the Contractor shall be performed from a floating plant, either on the upstream side or downstream side of the dam, or from a fixed platform. The minimum distance between the edge of the floating plant and the bulkheads shall be 3’. The contractor shall not tie off to the bulkheads in any way.

Spuds shall not be lowered onto the apron and/or stilling basing when the floating plant is on the downstream side of the dam; extents of the apron and/or stilling basin are provided in drawings and reference drawings. The Government will determine what flows the Contractor is able to safely operate the floating plant upstream of the dam; floating plant use upstream of the dam is restricted during high flow stages. The floating plant shall be powered by a vessel with no less than 1100 horsepower in order to safely maneuver the floating plant upstream of the dam.”

14) General Note 2 on page SB-401 calls for the entire structure above elevation 471.0 to be painted.

The Tainter Gate Repair Schedule on page SG-535 depicts the repair items and the cleaning & painting scope required for the elevation bellow elevation 471.0 There are some ladders and rails (RS-105,106 & RS-107/ interior and exterior) located in the area below the 471.0 elevation. Do those get painted?

RESPONSE: The handrails and stair treads shown on RS-106 for Pier No. 1, do not get painted. The ladder rungs below Elevation 471.0 for Piers No. 2 through No. 16, shown on RS-107 do not get painted.

The handrails and stair treads shown on RS-113 for Pier No 17, do not get painted.

15) Does the entire interstitial space of each tainter gate receive abrasive blasting and coating?

RESPONSE: The interior and exterior of the Tainter Gates are to be coated with System No. 5-E-Z, as described in Specification Section 09 97 02 Paragraph 3.5 “Painting Schedules”. All the rivets and gusset plates in the interior of the Tainter gates require abrasive blasting for Government inspection to determine which rivets and gussets require replacement, as described in Specification 09 97 02 Paragraph 3.1.5.

16) Are there any records or is it known what the existing coating system is on the interstitial space of each tainter gate?

RESPONSE: The repairs performed as shown in reference drawings RS-251 through RS-257 were coated with System No. 5-E-Z. The coating system applied to the other areas on the interior of the Tainter gate is not known. Test results from paint on the interior of Tainter Gate #1 from 2004 indicate lead, cadmium and chromium. Test results of the sediment on the interior of Tainter Gate #1 from 2004 indicate lead and other heavy metals. Test results from paint and sediment on interior of Tainter Gate #1 from 2004, along with a limited lead based paint risk assessment from 2013 for the project have been provided in Amendment 0001.

17) Given the amount of effort necessary by the contractor for this proposal and in full disclosure, we wanted to know if the USACE St. Louis District would accept a proposal with a schedule showing that we start in 2021 rather than 2020?

RESPONSE: Award of Contract is anticipated NLT 1 February 2020. The submittal process is expected to take approximately 6 months (approximately August 2020) after NTP which will be a partial NTP to complete submittals. As per Specifications, river based operations will only be permitted between 24 February and 30 November. It is likely the best interest of the Government to start construction at the beginning of the construction season in February 2021 after all the submittals have been approved. The issuance of task orders is based on available funding. The contract Length is based on 16 spans with 4 spans completed per year. 4 years for construction and 1 year for submittals. POP of each task order will be awarded as funding becomes available which may span numerous construction seasons over the course of the contract duration.

18) Lastly, what would be the response time required by the contractor once an order is received?

RESPONSE: The Contractor shall be required to commence work under this contract within 10 calendar days after the date the Contractor receives notice to proceed. See FAR 52.211-10 clause in this solicitation. NTP will be given individually for each task order, and typically within 30 days of task order award.

b. The Lock and Dam shall remain in operation during the construction period except as noted on the construction drawings or in the specifications, or as directed by the Contracting Officer's Representative. Lock and Dam operation takes precedence over construction Contractor operations. The Contractor shall coordinate all work with the Contracting Officer's Representative and the Lockmaster, including the setting and removal of Tainter gate bulkheads by the Government. The Contractor shall conduct its operations to not interfere with the functions of the Government personnel and the use of the lock by river traffic.

c. The Contractor will not be given priority over other waterway users for lockages. The Contractor shall adhere to normal queuing procedures as required unless otherwise permitted by the Lockmaster.

d. The Contractor shall be advised that no river based operations and/or gate work will be permitted under this contract during the time period of 1 December to 23 February due to cold temperatures and ice on the river. The Contractor shall remove floating plant from the immediate work site during this period (1 Dec to 23 Feb). The Government will remove bulkheads during this period. Any work started on any gate(s) prior to these dates shall be complete by 30 November such that all gates are fully operational during the period of 1 December to 23 February. Work on the service bridge during the aforementioned timeframe, that is not dependent on the use of a floating plant, will be considered by special request to the Contracting Officer for permission. Due to scheduled lock closures for LD24 and LD25 from 15 December 2019 to 31 March 2020, the floating plant access to the downstream side of dam is restricted.

e. Not more than two Tainter gates shall be out of service for rehabilitation at any one time. When two Tainter gates are out of service, the two gates shall be adjacent to each other. The amount of concurrent structural demolition/rehabilitation on two gates shall be limited as shown on the drawings. Gates on either side of the bulkheaded gate(s) will be adjusted by the Government to the extent permissible for the flow conditions at the time in an attempt to minimize turbulence below the gate being rehabilitated. The Contractor shall be responsible for monitoring water currents within work areas to maintain worker and equipment safety and coordinate all requirements for possible adjacent gate closures with the Government.

All requests by the Contractor, with respect to gate settings, will be coordinated with the Lockmaster. The Lockmaster is responsible for

DOCUMENT 00 08 00 Page 9 maintaining safety and operability of the lock and dam and will only concur and direct gate change settings as determined safe by the Lockmaster.

f. All work required in this contract, including proper containment and disposal of debris, shall be accomplished in place at Contractor's expense.

g. In order to perform required work on Tainter gates as specified in this contract, it will be necessary to close off flow to the gate bay. Emergency bulkheads for closing off the flow to the gates are stored in the storage yard at the east end of the dam. The Government will be responsible for transporting bulkheads from the storage yard, placement and movement of bulkheads. The Contractor shall schedule work within the following parameters:

1) The Government bridge crane shall not be available to the Contractor for any type of use. The Government will utilize the bridge crane for placing bulkheads.
